Metallic Materials and Processes Competence Center


metallic materials and processes

Our competence center plays an essential role in the development and qualification of materials and processes that contribute to the technical and economic competitiveness of metallic solutions in the structures and systems of aircraft, satellites, launchers, and turbine engines.



Our experts aim at bringing together, in the same team, scientific and technological skills that are both multidisciplinary and complementary. The mix enables us to transfer the results of research projects more rapidly to the industry. The range of competencies includes experts in physical metallurgy, process simulations, thermomechanical modeling, special processes, and physicochemical characterizations.

Through our strategy, we focus on eco-design, sobriety, and sustainability of metallic materials, structures, and systems. Development of tailor-made materials with specific properties (like architecture or functionally graded materials) supports our strategy, as well as material savings, streamlined structures, increased use of recycled materials, or deployment of repair solutions for high added value components.
